Vegas Pro Production Assistant 2 Batch processing .veg files

Just got Vegas Pro Production Assistant 2 and think maybe I misunderstood some advice someone gave me to buy this. I want it to batch render a folder of completed videos that now sit in the form of Sony Vegas 13 .veg files. Instead of me pushing render every hour or so to do so myself, it, I was told, would just process one after another. But, I'm not seeing how it does this....
